- <link href="" ... was not recognised if > 1 space between words
- #Content p em { font-style:italic; } was applied to "#Content p"
- @import url() embedded in a stylesheet file requires path fixed relative to stylesheet file
- background-image url() embedded in a stylesheet file requires path fixed relative to stylesheet file
- comment tags inside CSS <style> embedded in the HTML were removed
Now fixed so <style><!-- ... --></style> works; <!-- <style>...</style> --> is removed
Bug fixes (other)
-----------------
- clear (CSS property for floating elements) caused properties for that element to reset to defaults
- width: auto caused collapse of border and padding on L & R of ordinary block elements
- text-indent not inherited correctly (including em and % values)
- named colour "steelblue" corrected RRGGBB hex code
- table cell widths in %: if width of table cells set to >=100%, and not all columns are set
This was fixed in 3.2 but led to problem where 2 cols: 1) 80% and 2) not set (see Table sizing test)
Now fixed again to work for both(?)
- parse PNG error fixed
- bachground-image not correctly positioned in HTMLFooter and HTMLHeader (Not fixed properly in 3.2!)
- fonts not supported with 0-9 in the name
- font list in GetCodepage() in htmltoolkit.php (now config_cp.php) containing space " " not recognised
- list number positioning
- list font size set in CSS for UL/OL not working for first level list
- table width (real value, not %) not working in nested table
- GIF file failed if PDF file not compressed
- list-style-type incorrectly inherited
- line-height inheritance in lists
- SetColumns added a new line - not required if at start of document/page
- footer_line_spacing did not work
- table cellPadding="" overwrote cell padding set on cell CSS
- could not turn off Default non-HTML foter LINE
- border specified as "em"
- default values set in mpdf.css overriden by inherited properties e.g. <div><h1>Here</h1></div> lost font-size for H1
===========================
mPDF v3.2 (25/10/2009)
===========================
Bug fixes
---------
- Table cell widths in %: if width of table cells set to >=100%, and not all columns are set -> froze, because tries to produce a column of no width
- Ouput download file changed to allow compatability with IE6 (http://mpdf.bpm1.com/forum/comments.php?DiscussionID=120&page=1#Item_4)
- Image error if relative path used on domain root (e.g. img src="image.png" and basepath is http://www.yourdomain.com) [attempted fix in 3.1 not working]
- Table: if font changed in cell, font was not retoring properly afterwards causing errors (restoreInlineProperties())
- Lists: list items containing <br />, font not restoring after bullet
- Graceful support for block elements inside list items e.g. <li><p>... (not supported, but tolerated)
- Index: Created dividing letters separately for Uppercase and lowercase
- Incorrectly changing input character set when encountering e.g. charset=iso-8859-1 in the text of the document
- Changed so only detects it if within <head>...</head>
- If Keep-with-table (i.e. H1-6 before table and use_kwt true), if pagebreak forced anyway, borders did not print on previous page
- Background-image used in HTML footer not appearing (correctly)
- RTL tables: nested tables will not automatically transpose L->R
- "Keep heading with table" - changed to allow <h1 style=".."> not just <h1>
- "Keep heading with table" - backgrounds (bgcolor, image or gradient) incorrectly handled - now removed
- Rotated table spread over more than 1 page caused enclosing block background colours to be be rotated along with table
- CSS text-indent % now correctly suported (% of containing block width)
- CSS width em on a block element e.g. DIV now correctly suported
- calculating _tableheight, if remainingpage==0, get error (div by zero)
- Table moved to next page with page-break-inside=avoid, produced an enlarged table (font)
- RTL text-align override on BODY text was not working consistently
- Arab characters: Character ه (HEH) appearing in Final presentation form instead of Isolated
- Vertical position of background-image on whole page incorrect
- SetProtection can now be used with no permissions set (was not working unless at least one permission set)

----------
Some more undefined indexes and variables declared (courtesy of DSmart http://mpdf.bpm1.com/forum/comments.php?DiscussionID=117&page=1#Item_0 )
Comment lines removed for < v3.0 to tidy up code
Enhancements
------------
CSS style height now partially supported on block elements DIV, P, H1 etc. --IF--
- block is all on one page
- will extend the block but not shorten it
- will not force a pagebreak (max. at bottom of page)
- % is interpreted as % of printable page height (inside margins)
<TFOOT> now supported (placed at start as in HTML spec) displays at end of table, and repeats as a footer
Background-image and background-gradient now supported in TD and TH (works in all cases except: background-image is not rotated or
positioned correctly if table is rotated)
NB Background images and background-gradients do not work if Columns are being used, or if $use_kwt is TRUE (keep-with-table),
or if page-break-inside:avoid is active.

mPDF<=3.1 generated a large number of warning "Notices" if run with full eror_reporting on, due to array indexes not being initiated e.g.
$arr = array();
...
if ($arr['index'] == 5 ) {...}
To prevent this, lines were added at the start of the mpdf.php script to turn error notices OFF.
In a move towards making mPDF able to run with full error_reporting on, a large amount of the script has been altered
e.g. the line above would be changed to:
if (isset($arr['index'] && $arr['index'] == 5 ) {...}
Although I have tested this with a number of examples, it is almost certainly not complete. Therefore the error_reporting for Notices is still turned
off in mPDF 3.1
If you care to test it, please uncomment line 43 (//error_reporting(E_ALL);) and report any warning notices that you get.
NB This has added about 40kB to the script size.
===========================

- Background gradients (linear or radial) can be defined using a custom CSS style property
- Border radius can be defined to give rounded edges to block elements (uses draft CSS3 spec.)
- page number can be reset to any value during the document (in AddPage() <pagebreak> etc.)
- PNG images: Interlaced and alpha-channel-set PNG images now supported
- internal links supported in Indexes (parameter added to CreateIndex()/CreateReference(): $useLinking=true;)
- HTML Headers and footers now support hyperlinks

- Internal links (anchors) - Annotation/Bookmarks etc. incorrectly positioned when page orientation changed
- ToC - when using multiple ToCs, internal links were not correctly adjusted
- anchor (a name="") used inside a table was incorrectly positioned at the end of table
- Tables: cell height calculated incorrectly when BR used
- Table rotated with "page-break-inside:avoid" not kept on one page

Fonts in CSS - CSS font-family: [unknown]; setting first $available_unifont rather than ignoring
Images - not displaying on IIS platform
Images - .wmf not displaying if (allow_url_fopen) not set
Table borders - in defaultCSS, 'MARGIN-COLLAPSE'=> collapase not quoted therefore not working
Line-break inside table - printing a blank background across page rather than just going down a line
Form fields inside tables - will now resize if the table is autosized (shrunk)
<pre> containing a '<' was changed to '<'
Tabs inside <pre> were all changed to 8 spaces, not the remainder following a string

mpdf.css (new)
===========================
New files from mPDF <2.0 (only required for EAN Barcodes)
font/ocrb.xx (several)
unifont/ocrb.xx (several)
IMPORTANT - you need to make sure the ocrb font is added to the config.php file
- add 'ocrb' to the end of 3 arrays: $this->available_fonts $this->available_unifonts and $this->mono_fonts
===========================
Summary of changes
- external stylesheet file (mpdf.css) is used to configure default values ($useDefaultCSS2 and $defaultCSS2 are no longer used)
- special comment tags to hide mPDF tags from browsers: <!--mpdf ... mpdf-->
- AddColumn() function added (equivalent to <columnbreak>)
- annotations - pop-up messages the reader can move or delete (if you set permissions)
- support for WMF images as well as GIF, JPG, PNG
- watermark image can be set instead of, or as well as text
- nested tables can include other content
- improved control over table layout
- margin: auto now supported for table and block elements
A number of methods and variables have been renamed or reCapitalised for consistency.
Changes should be backwards comaptible.
All user methods start with a Capital, all user-defined variables start with lowercase.
Affected:
Reference() -> IndexEntry()
CreateReference() -> CreateIndex()
$TopicIsUnvalidated -> $showWatermark
setUnvalidatedText() -> SetWatermarkText()
PHP appears at present to be case-insensitive for function/method names
All the following functions have been renamed in the script with a capital first letter:
setUserRights()
setBasePath()
setAnchor2Bookmark()
setHeader()
setFooter()
defHeaderByName()
defFooterByName()
setHeaderByName()
setFooterByName()
setHTMLHeader()
setHTMLFooter()
defHTMLHeaderByName()
defHTMLFooterByName()
setHTMLHeaderByName()
setHTMLFooterByName()
shaded_box()
writeBarcode()
Variable names changed to lowercase first letter:
(Variables are case-sensitive therefore aliases have been set up)
Anchor2Bookmark
BiDirectional
KeepColumns
AliasNbPg
AliasNbPgGp
=========
Bug fixes
=========
Columns - $keepColumns=true was incorrectly calculating the place to continue printing after 1 and half columns (of 3)
Table cell height - incorrectly setting table cell height when cell contained a line of text of large size which wrapped to more than one line
HR in Table cell - if table cell contains only HR (and column otherwise empty), HR was printed outside cell
HR in Table cell - if table cell ended with a HR, height was one line too much
Table page-break-inside:avoid - caused mPDF into permanent loop in some circumstances
Paging - Total Pages/Group {nb} and {nbgp} didn't work in CJK
CSS - Border size thin, medium and thick were only recognised in lowercase
Table-header - rowspan not correctly output in THEAD
Default CSS - table empty-cell:hide changed to show (CSS specification)
===========================
mPDF v2.1 (24/01/2009)
===========================
New Features in Version 2.1
---------------------------
- CSS support improved generally (especially for cascading CSS, lists)
- TableHeader changed to allow multiple rows in THEAD
CSS changes
-----------
- display: none (block elements only - not lists or tables, nor HR)
- width (TD/TH)
- list-style-type (will also recognise the list-style-type from list-style) (OL/UL)
- CSS support for <LI>: font-family, font-size, font-style, font-weight, color, background-color, text-decoration, text-transform, and list-style-type (will also recognise the list-style-type from list-style)
- table cell borders - CSS rules have been adapted slightly - if a coloured/black line conflicts with a white line, and is the same width, coloured/black will overwrite even if Bottom or Right
Numbered Lists
--------------
Variables set at the top of mpdf.php can be set to change:
- text alignment of numbers in numbered lists (default Right)
var $list_align_style = 'R';
- content to follow a numbered list marker e.g. '.' gives 1. or IV. whereas ')' gives 1) or a)
var $list_number_suffix = '.';
(These can be altered at run time, but are not changeable through stylesheets or in-line style)
Writing broken segments of HTML
-------------------------------
2 new parameters have been added to WriteHTML()
function WriteHTML($html,$sub=0,$init=true,$close=true) {
$close - Leaves buffers/variables etc. in current state, so that it can continue to write the HTML where it leaves off
$init - Clears and resets buffers/variables
(N.B. You must end with a WriteHTML that calls $close=true)
Example:
$mpdf->WriteHTML('<p>This is the beginning...', 2, true, false);
$mpdf->WriteHTML('...this is the middle...', 2, false, false);
$mpdf->WriteHTML('...and this is the end</p>', 2, false, true);
Rotated text in table cells
---------------------------
NB This UPDATE will change expected output from previous versions******
Prior to v2.1 any cell set to rotate text anticlockwise was forced to vertical align = bottom.
This has been changed so that it only overrides when the rotate angle is between 45 and 89 degrees: text rotated exactly 90 degrees will respect the set value for vertical-align.
=========
Bug fixes
=========
- List - list starting after "<div>Then some text not in a block element<ol>" incorrectly output
- Tables - if cell font-size set smaller than default for the table, does not shrink the cell height
- Columns (tables) - columns breaking across rows e.g. in the middle of a table cell
- Tables - if table width set to e.g. 100% but cols are less, was not making up to set width
- Watermark - was not printing if using HTMLFooter
- Lists - not aligning numbering correctly if different font sizes used for bullet & text etc.
- Lists - indent of text did not correctly allow for Maximum number in <ol> list
- Table does not always move correctly to a new page
- Table cell incorrectly calculated height causing text to overflow cell when printed
- Table borders in columns not being correctly handled (bug since 2.0 introduced a buffer to save the borders and print at the end of the table - fixed so does not use buffer if in columns - potentially does not deal with conflicting borders as well, but works in columns)
- Table cell width if set as a percent was being downsized when autosizing table
- Table CSS was buggy - improved
- SetBasePath (when fetching remote website) - now handles string with query string on it e.g. http://www.domain.com/index.php?tid=42
- Table cells with Rotated text - text not positioned correctly
- Page number totals not working in utf-8 mode
============================
Code efficiency improvements
============================
- BIG speed improvement (compared with 2.0) with tables (especially large tables)
- considerable increase in speed if writing long HTML segments to mPDF
- speed improvement for tables (may be very significant if some cells have a lot of text in them causing uneven column widths)
NB To speed up program more, consider setting $mpdf->useSubstitutions=false; if you do not use any characters outside the codepage selected
===============
Keep-with-table
===============
(This was introduced in v2.0 but I forgot to document it)
If you set $this->use_kwt = true;
All H1-H6 elements will try to keep with a table that follows immediately afterwards - (this is done in htmltoolkit, by adding an attribute KEEP-WITH-TABLE)
See Known Issues re: Using kwt inside a div with border/background (doesn't work)
===========================
mPDF v2.0 (07/12/2008)
===========================
Main New Features in Version 2.0
- nested tables are supported
- supports both models of table border: separate and collapsed
- improved parsing of CSS stylesheets, and better handling of styles throughout
- additional recognised CSS styles
- page orientation, size, and margins can be changed within the document, using PHP script or custom HTML
- some limited support for @page CSS to define page-box areas, with crop/cross marks for printing
- improved control over headers and footers (including HTML headers/footers)
- improved presentation of Form elements including image-type input fields
- generates an EAN barcode suitable for a book/printed publication
- active forms can be generated - EXPERIMENTAL at present
- change document permissions to allow the user to make annotations - EXPERIMENTAL at present
NB Lines are commented in mPDF script as changes for mPDF 1.4 - this became v2.0
=========
UPGRADING
=========
IMPORTANT - Before Upgrading: Please note that some of the changes will cause mPDF 2.0 to render the pages differently from earlier versions i.e. it is not totally backwards comaptible. Read the notes on Backward compatibility before deleting your original set-up.
To upgrade from v<=1.3 to v2.0 you only need to copy and overwrite the following 2 files:
mpdf.php
htmltoolkit.php
Plus (optionally) if you want to use the EAN Barcode function, you will also need:
font/ocrb.xx (several)
unifont/ocrb.xx (several)
IMPORTANT - you need to make sure the ocrb font is added to the config.php file
- add 'ocrb' to the end of 3 arrays: $this->available_fonts $this->available_unifonts and $this->mono_fonts
==========
Bug Fixes
==========
<columns column-count="0"> did not turn off columns - Fixed
Margins as % - e.g. margin-right: 50% set from CSS incorrectly applied 50% of the fontsize
(Fixed - adding parameter to fn. ConvertSize in htmltoolkit.php and in calls to that function)
DIV Width - e.g. div style="width: 50% was not working
(Fixed - fn.SetCSS and OpenTag()'DIV')
CSS values as Zero - p { margin: 0; } did not work in stylesheet unless 0 had a unit
Multiple Non-breaking spaces collapsed - e.g. "1 2" - was contracted to "1 2"
(Fixed - fn.adjustHTML in htmltoolkit.php)
Table cell too narrow causing incorrect printing - If two characters are too wide to print (only likely within a table cf. example tables - Periodic table) the first character was not printed, just a new line
(Fixed in fn.WriteFlowingBlock)
Font size by inline style for form elements <input> <textarea> gave wrong size when using a relative size 0.9em
(Fixed - fn.ConvertSize in htmltoolkit.php)
Creation Date not correctly showing
(Fixed - did not need to convert to UTF16)
New block element started at end of page - block borders not painted
(Fixed - fn.AddPage)
DL did not close block correctly
(Fixed - mistype in fn. CloseTag)
Transparent not recognised as color/background-color
(Attempted a fix by setting to ignore it! - fn. convertcolor in htmltoolkit.php)
Zero (0) not displaying if only thing in table cell or tags e.g. <td>0</td> <p>0</p>
(Fixed - fn.WriteHTML)
Page Headers/Footers - Simple Headers or Footers defined as e.g. '|{PAGENO}|' were not split into 3 components, but output |6| in the outer margin.
(Fixed)
Could not copy from a completed PDF doc to clipboard when using a TrueTypeUnicode font
Creating an Index (confusing called CreateReference in mPDF) based on only 1 column (i.e. columns off) caused it to print FAIL
(Fixed - fn. CreateReference())
Table of Contents - If a ToC entry reached other side of page a warning notice was produced
Fixed - printing is now suppressed and it is moved down a line (but not when using rtl)
"Keep Block Together" (i.e. page-break-inside: avoid for a block element)
If this property causes some text to be moved to the next page, internal link targets (i.e. <a name="xxx">) were incremented pagenumber by +1 - as this used the calculated document page number, didn't work if using e.g. roman numerals
(Fixed)
NB This is now ALWAYS disabled when it meets a table - can use page-break-inside:avoid for the table
@import url(style.css) without quotation marks "" was not picked up, although it is valid HTML
(Fixed - fn.ReadCSS())
Reading CSS from external style sheets included all media
Now set by default to ignore media="aural|braille"
Allows media="print" but can exclude by: $mpdf->disablePrintCSS = true; (default = false)
Works on both <link... and <style media="print">@import...
See the web page example - this stops the CSS stylesheets specifically marked for "print" to be ignored
Table borders (in collapsed model) incorrectly calculated which border had dominance (mPDF <=1.3 determined the overriding border by its color)
(Fixed to follow CSS 2.1 specifications: width >> CSS dominance (cell>table) >> T & L > B & R)
In the border-collapse=collapse mode, the following rules determine which border style "wins" in case of a conflict:
1. Borders with the 'border-style' of 'hidden' take precedence over all other conflicting borders.
2. narrow borders are discarded in favor of wider ones.
3. styles are preferred in this order: 'double', 'solid', 'dashed', 'dotted', 'ridge', 'outset', 'groove', and the lowest: 'inset'.
4. If border styles differ only in color, then a style set on a cell wins over one on a table.
5. When two elements of the same type conflict, then the one further to the left or top wins out.
Parsing CSS, a missed level would not be picked up i.e. CSS = div.refstr1 p {...} would not pick up:
(Fixed - fn. MergeCSS by carrying everything forwards)
Note: I removed - && !$this->blk[$this->blklvl-1]['cascadeCSS']['CLASS>>'.$attr['CLASS']]['depth']
Not sure why I put it there in the first place!
In a later bit of function - && $this->blk[$this->blklvl-1]['cascadeCSS'][$tag]['depth']>1
Haven't removed this, but is it needed???
CSS inline style set in TD/TH (font-size, color, weight, font-family or italic) didn't turn off at the end of the cell (and also formatted the top left cell)
(Fixed)
CSS properties color, font-weight, and font-style set on a table were not inherited by the table cells
(Fixed - var $base_table_properties)
When rotating a table, the text following was positioned incorrectly
(Fixed - fn. printtablebuffer)
When rotating a table, links were not adjusted in position e.g. <a href="">...
(Fixed - fn. printtablebuffer)
If a larger border-thickness was set for a cell in the middle of a table, cells before that inaccurately calculated the cell wdith needed
(Fixed)
Text in a table cell which was not in a block and followed a list, there was no line break e.g. </ol>Text following</td>
(Fixed - var $listjustfinished;)
Setting the default font-family from the body tag using in-line CSS did not work e.g. <body style="font-family:mono"> (did work in external stylesheets)
(Fixed - fn.WriteHTML)
<link href="..." rel="stylesheet"> was not recognised (because the href comes before the rel)
(Fixed)
Read linked CSS stylesheet OR @import stylesheet - now includes both.
<tag class="class1 class2"> did not set either class1 or class2. Fixed so that it will now pick out class1 (better than nothing!)
CSS line-height as % - interpreted 120% as 120 (x the font-size) - Fixed so it now accepts % and numbers
Setting the basepath (used for relative links/external stylesheets etc) with $mpdf->setBasePath() was generally buggy!
Now allows a domain e.g. $mpdf->setBasePath("http://www.domain.com"); (previously needed slash on end)
(Fixed - hopefully!)
If you were repeatedly calling mPDF in a loop to produce more than one PDF file, it would crash with error: "You have restricted the number of available fonts to 0". Fixed by editing line 751 require(_MPDF_PATH.'mpdf_config.php'); to require(...
=============
Improvements(?)
=============
Unsupported image files - mPDF died with an error message if image files didn't meet expected format e.g. an interlaced PNG file
Changed so images are now replaced by the NOIMG image.
Footer margin (HTML and normal footers) now determines the lowest point that is printed (rather than the place to start printing the footer)
NB IMPORTANT CHANGE - not backwards comaptible
Tabs in <pre> or <textarea> are now replaced by 8 spaces rather than 6 (consistent with http://www.w3.org/TR/1998/REC-html40-19980424/struct/text.html#edef-PRE) [fn. AdjustHTML() in htmltoolkit.php]
To insert the total number of pages in the document anywhere in the doc, just use '{nb}'
The line: $mpdf->AliasNbPages();
has now been uncommented allowing {nb} to be used
NB This will always give the total no. of pages in the whole document regardless of any changes you have made to page numbering.
You can change the default placeholder '{nb}' to any string using: $mpdf->AliasNbPages('[**my Chars**]');
$mpdf->AliasNbPageGroups(); default="{nbpg}"
Can be used to set the total number of pages in the current group i.e. between where page numbering is reset
CSS border correctly fixes "solid 3mm #000000" i.e. (style width color) - (not a bug, but this is often incorrectly specified)
Can now print div background behind a rotated table.
You can keep columns as they are i.e. 1st column will finish page then start on second, by setting
$mpdf->KeepColumns = true;
Image constrain
===============
Image size is constrained to current margins and page position. Extra parameter added to end of fn. allows you to override this.
$mpdf->Image('files/images/frontcover.jpg',0,0,210,297,'jpg','',true, false); // e.g. the last "false" allows a full page picture
Useful for e.g. a cover page for your document
Cumulative CSS
==============
In version <=1.3, if you call:
$mpdf->WriteHTML($stylesheet,1);
$mpdf->WriteHTML($html); // this one cleared the array $this->cascadeCSS; conatining cascaded CSS information from stylesheets
You were meant to call:
$mpdf->WriteHTML($html,2); // which doesn't re-parse the CSS information
v2.0 changed so that
$mpdf->WriteHTML($html); no longers clears the array $this->cascadeCSS and so can be used repeatedly;
================================================
Additional CSSstyles & HTML attributes supported
================================================
<BODY> - font-style, font-weight, color
<IMG> - html attributes width="" and height=""
<TABLE|TD|TH> - border: 'thin' 'medium' and 'thick' are now converted to 1px, 3px and 5px
<TABLE|TD|TH> - border now respects all types - e.g. 'double', 'solid', 'dashed', 'dotted', 'ridge', 'outset', 'groove', and 'inset'
(NB mPDF only supports a full declaration of border e.g. "border: thin double #000000;")
<TD|TH> - CSS style="white-space: nowrap" and HTML attribute nowrap="nowrap"
<TABLE> - page-break-inside: avoid
<TABLE> - border-collapse: separate|collapse
<TABLE> - border-spacing: 2px 2px; (horizontal/vertical) or just one figure (both) NB same as cellSpacing
<TABLE> - margin-left and margin-right (previously only supported top and bottom)
<TABLE> - padding: (this was incorrectly used for TD/TH before) (border-collapse:separate only)
<TD|TH> - padding:
<TABLE|TD|TH> - inline style "background" works (with a color only) the same as "background-color"
NB Table page-break-inside, autosize values and rotate are only respected for that set on first level table of nested tables
<TABLE> - cellSpacing and cellPadding HTML attributes:
NB cellSpacing is the same as CSS style "border-spacing"
NB cellPadding is a <table> attribute, but sets the cell padding - not table padding
<TABLE> - align="..." now works with a rotated table - but sets the alignment ignoring the rotation i.e. align=right sets the table to the right side of the page (looking as though it is bottom-aligned)
<BLOCK ELEMENTS> - page-break-before: always|left|right - NB any surrounding block tags will be closed before the new page is inserted.
@page - see notes on Paged Media
==========================
Unsupported HTML attribute
==========================
<TD border="1"> - not valid HTML - no longer supported
=========
Additions
=========
"Keep-with-table"
$mpdf->use_kwt = true; // default=false
If set to true, will force any H1-H6 header immediately preceding a table to be kept together with the table
- automatically sets the table to fit on one page (i.e. page-break-inside=avoid) if it is a rotated table
- ignored if: Columns on, Keep-block-together active (page-break-inside=avoid for surrounding BLOCK), active Forms
=====
Notes
=====
NB Not a change - but note you can use this to allow you to feed html code encoded in other than utf-8:
$mpdf->allow_charset_conversion=true;
$mpdf->charset_in='windows-1252'; (needs suitable codes for iconv i.e. windows-1252 not win-1252)
Fixing Optional tags
====================
php.net website has illegal nesting of <dt>.. <dd> .. </dd> .. </dt> and <p>.. <div> .. </div> .. </p>
The example wich parses the php.net webpage will not show correctly unless you change: $mpdf->allow_html_optional_endtags=false;
Trying to fix incorrect (X)HTML with $mpdf->allow_html_optional_endtags==true cancels the P when it meets a DIV etc.
"<22><><EFBFBD>" used as a special identifier in the program changed to "\xbb\xa4\xac" to make the mpdf.php script file immune from someone saving it as a utf-8 encoded file
1) When copying remote images locally - incorrectly used "unset" now changed to "unlink"
2) When parsing image files - was using CURL for any image src="http://... - even if this was on the local server - edited so it only uses CURL if necessary/appropriate.
NB Handling images was updated in v1.3 because my ISP changed allow_url_fopen to false
Fixed so mPDF tests if the file is available as a local call e.g. getimage('images/test.jpg') even if it is defined as a full URI e.g. http://www.mydomain.com/images/test.jpg as this is quicker(?), and permitted even if allow_url_fopen is false.
If not available as a local file (and allow_url_fopen is set) mPDF tries to use fopen/file_get_contents using an http wrapper;
Else, if CURL is available and allow_url_fopen is false: then tries using CURL.
(Clear as mud???!!)
===========================
mPDF v1.3 (21/09/2008)
===========================
--------------
Page Numbering
--------------
Program changes:
fn. startPageNums() replaced with blank function
fn. stopPageNums() - deleted
fn. numPageNo() - deleted (all it did was return this->page anyway).
var $_numbering - deleted
var $_numberingFooter - deleted
var $_numPageNum - deleted
NEW
New: fn. AddPages() (as for AddPage but with type=NEXT-ODD or NEXT-EVEN see below)
<pagebreak type="NEXT-ODD" // always adds a page + another if required to make odd
<pagebreak type="NEXT-EVEN" // always adds a page + another if required to make even
Edited: fn. TOC() // sets the marker for a Table of Contents
New parameters allow the page-numbering details to be set
NB the page-numbering details set are for the page which follows on after the TOC marker is inserted. The page-numbering for the actual ToC is set later, when the ToC is generated and inserted here
new parameters as above for pagebreak resetpagenum="1|0", pagenumstyle="I|i|A|a|1", suppress="on|off"
New custom style or attribute -- "text-rotate" -- can be set for either <tr> or <th|td>
Allowed values: 45 - 90 (written as integers) - rotates text anticlockwise, and -90 (clockwise)
Positive values less than 90 force cell to: vertical-align:bottom
Limitations:
Only allows single line of text;
Font, font-size, and style are determined by those set fro the cell, and cannot be changed;
No changes in font (or any other in-line changes e.g. <sup>) are supported within the text
Example: <tr style="text-rotate:90">...
---------
Bug fixes
---------
1) HTML footer containing table was triggering page break.
Added $this->InHTMLFooter as flag to prevent page triggering in footers containing table
Set in fn.writeHTMLFooters() -> in fn.tableWrite() stops the pageBreak being reset
2) Crashing when libcurl not installed.
Edited OpenTag() curl_init - added if (function_exists) to exclude crash when libcurl not installed
3) Single cell with borders not showing the borders.
e.g. <table><tr><td style="border:1px solid #000000?>Hi</td></tr></table>
Problem: mPDF overrides cell border properties with table border properties for external borders. $defaultCSS had CSS defined for table as '0px solid #000000'
Quick fix - line 273 removed. A more complete fix will require reprogramming to distinguish between "border property not set" and border property set as "none".
4) Empty textarea incorrectly handled (the following HTML code being output in the textarea)
The html code for an empty textarea was incorrectly handled in htmltoolkit fn. AdjustHTML which has been edited
===========================
mPDF v1.2 (2008-05-01)
===========================
// Added v1.2 option to continue if invalid UTF-8 chars - used in function is_utf8()
var $ignore_invalid_utf8 = false;
Reading CSS in fn. ReadCSS() and applying in fn. MergeCSS() -
Edited to allow Tags, class and id with the same name to be distinct i.e. h5 {...} .h5 {...} #h5 {...}
* mPDF 1.2 This version supports: .class {...} / #id { .... }
* ADDED p {...} h1[-h6] {...} a {...} table {...} thead {...} th {...} td {...} hr {...}
* body {...} sets default font and fontsize
* It supports some cascaded CSS e.g. div.topic table.type1 td
* Does not support non-block level e.g. a#hover { ... }
Table: font-size, weight, style, family and color should all work
TD/TH: font-size, weight, style, family and color should all work
Added to htmltoolkit - fn.array_merge_recursive_unique()
memory_opt Removed in mPDF v1.2 - not working properly
fn. _begindoc() - changed to %PDF1.4 (was 1.3) as PDF version
Write HTML Headers and Footers
------------------------------
fn. Close() - calls writeHTMLHeaders/Footers() before finishing doc
fn. WriteHTML() - added parameter
fn. _out - writes to outputbuffer when writing HTML footers/headers
